Sexual dimorphism is a pervasive phenomenon among anthropoid primates. Comparative
analyses over the past 30 years have greatly expanded our understanding of both variation …

In comparative studies of sexual size dimorphism (SSD), the methods used to quantify
dimorphism are controversial. SSD is commonly expressed as a ratio between species …

Group size covaries with relative neocortical volume in nonhuman primates. This regression
equation predicts a group size for modern humans very similar to that for hunter-gatherer …

We review evolutionary processes and mechanisms that gave rise to the diversity of primate
social systems. We define social organization, social structure and mating system as distinct …

The last decade's lemur research includes successes in discovering new living and extinct
species and learning about the distribution, biogeography, physiology, behavior, and …

Numerous studies use estimates of sexual dimorphism in canine tooth size and body weight
to support speculation about the behavior of australopithecines. However, the range of …

A number of factors, including sexual selection, body weight, body-weight dimorphism,
predation, diet, and phylogenetic inertia have been proposed as influences on the evolution …

In the 1970s, mid‐Pliocene hominin fossils were found at the sites of Hadar in Ethiopia and
Laetoli in Tanzania. These samples constituted the first substantial evidence for hominins …

Sexual size dimorphism is generally associated with sexual selection via agonistic male
competition in nonhuman primates. These primate models play an important role in …

Body weight dimorphism in anthropoid primates has been thought to be a consequence of
sexual selection resulting from male‐male competition for access to mates. However, while …
